[Users] oVirt 3.4.0 beta 2/Test Day
by Yaniv Bronheim 13 Feb '14

13 Feb '14

Hey all, I'm testing ovirt-live which takes me more than 1 day I followed the instructions in http://wiki.ovirt.org/OVirt_Live#VM to run in on a local vm the iso file I tried to took from latest build (jenkins.ovirt.org/job/ovirt_live_create_iso/) and sent mail to infra maillist that the link somehow fails to be d/led. currently opened 2 bugs https://bugzilla.redhat.com/show_bug.cgi?id=1063680 https://bugzilla.redhat.com/show_bug.cgi?id=1063829 and still playing with the ovirt-engine installation that doesn't work smoothly (at least from my prospective and tries) Regards, Yaniv Bronhaim.

[Users] New oVirt Community Dashboard
by Brian Proffitt 13 Feb '14

13 Feb '14

With much pleasure, I would like to introduce a new tool for the oVirt community: a community dashboard from the team at Bitergia. This dashboard, found at [1], should enable us to get better insights into the activity within our community, as well as what communication channels are performing the best and who is most active on any given day. Thanks to the work of Bitergia and Dave Neary, this dashboard is now ready for community feedback. I would invite you to take a look and make comments on how the information is presented and what data is available. Currently, the data is updated once a day. Two initial questions: would IRC data be useful? And, would an aggregate page of all of the "Top" lists be something to add, too? Two known bugs: The links to the MySQL and JSON data files are not working at the moment. We welcome your feedback! Peace, Brian [1] http://www.ovirt.org/stats -- Brian Proffitt - oVirt Community Manager Open Source and Standards, Red Hat - http://community.redhat.com Phone: +1 312 477 4320 / Cell: +1 574 383 9BKP IRC: bkp

[Users] ovirt test day 2
by Yair Zaslavsky 13 Feb '14

13 Feb '14

Hi, I tested the following: https://bugzilla.redhat.com/1053646 easily collapsible left-pane - was not included in test day 1 (I was supposed to test it back then) - works fine. https://bugzilla.redhat.com/1054209 - read only disks - works fine. https://bugzilla.redhat.com/1054219 - Only comment is - IMHO it should be considered having disks marked as read only (where applicable) in templates -> disks and perhaps also when showing the disks of each snapshot. other bugs opened: https://bugzilla.redhat.com/show_bug.cgi?id=1064601 Yair

Note that there are 2 memory usage reports; one for the host, and another for each VM. My response is related to the host, while the original question was for the VM. I still think the root cause is the same (ie- related to overcommitment; for example the VM may have a balloon inflated), but would like to properly check and fix if needed. In order to make sure we keep track of it, please open a bug with all the relevant info. Thanks and keep reporting! Doron

[Users] taking advantage of extra disk space on nodes
by Robert Story 13 Feb '14

13 Feb '14

--Sig_/3JPaVh0uh3olCd4JN0DHdY. Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable So I've got a handful of oVirt nodes now, and most of them have over 100G of unallocated disk space. I'm trying to figure out how to best take advantage of that space. I see two possibilities: storage for oVirt, or backup/archive storage. I'm currently using a single NFS server for VM/iso/export storage (oVirt 3.3.x on CentOS, if it matters) and don't need to scale to hundreds of nodes (probably 10-20, max). Is current gluster support stable enough for production? What are the pros/cons of gluster vs NFS? I like the idea of not having a single point of failure but worry about performance. The other option is to stick with my NFS server and use the extra storage for archive/backup space. Here I'm looking for reliability (i.e. losing a server won't cause data loss) over performance. Are there pros/cons to gluster vs ceph? Will either/both peacefully co-exist with an ovirt node? All suggestions welcomed. Thanks!

[Users] test day help -- console
by Greg Sheremeta 13 Feb '14

13 Feb '14

I'm having a tough time getting a VM console working via VNC. I set a VM to use VNC, and I installed virt-viewer. 1. When I try to open a .vv file with virt-viewer, I get an error "Cannot find guest domain /var/tmp/console.vv" 2. Using a VNC client to connect to the host with the password in the .vv file just immediately disconnects it -- no error message. 3. noVNC just gives me an empty popup with a gray background. Any ideas? Greg Sheremeta Red Hat, Inc. Sr. Software Engineer, RHEV Cell: 919-807-1086 gshereme(a)redhat.com

[Users] Dedicated Bonding interface for Gluster
by ml ml 13 Feb '14

13 Feb '14

Hello List, i would like to use a dedicated Bonding Interface for Gluster Replication and Migration. I was already able to add my Bonding Interfaces in my Hosts-Network Tab, however i am failing to tell Gluster to use this interface. It only offers me nodeX.local (which is my managment network). More infos are collected here: http://oi58.tinypic.com/v6qaa1.jpg Can someone tell me how to configure Gluster to use the dedicated bond interface? I already asked in the IRC Channel but nobody seems to know :-/ Thanks, Mario

[Users] actual disk size of vm via api
by Sven Kieske 12 Feb '14

12 Feb '14

Hi, I got a question regarding the reported actual disk size of a vm. you can obtain this value fine via api: https://your_engine/api/vms/{id}/disks/ however, if the vm is cloned from a template this disk size does not seem to show the actual size of the whole disk but instead the difference from the actual template size. is this a bug or a feature? I would like to obtain the "real" size. e.g. I have a template with 50GB (thin provisioned) the actual size of this template is 1,5 GB I clone a vm from this template, the actual size which gets reported via api is about 8 MB (stuff that changes from the template). So I can not obtain the complete used size of the vm. This was tested under ovirt 3.3.2 -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

First you will need to create a VM manually, install the cloud-init package, and then make a template from this VM.

Re: [Users] [Freeipa-users] RHEL 7 beta trust - slow domain user authentication to Linux hosts
by Steve Dainard 12 Feb '14

12 Feb '14

+Ovirt users mailing list - might find this interesting. Quick background: IPA server with cross-forest trust to Windows domain. Authenticating to Linux clients with domain kerberos credentials. I'm hosting CentOS 6.5 as an ovirt guest, and have narrowed this ipa client slow login issue down to a backend storage cause. If I enable async writes to NFS the CentOS guest performs as my workstations virtualbox guests (Ubuntu 13.10/Fedora 20) do on login (quick logins). The client we are investigating is a CentOS 6.5 machine. I've also done the same test on a RHEL 6.5 machine with the same results. I've increased the logging level, log attached. I don't see the DC in the logs anywhere. I guess from an IPA perspective there is not much to be done, but I wanted to make sure this thread came to some conclusion for future readers. I suppose the only thing to question, is why ipa authentication would have any reliance on disk read/write speed to this extent? Perhaps we are caching something to disk that should be cached in memory? *Steve Dainard * IT Infrastructure Manager Miovision <http://miovision.com/> | *Rethink Traffic* *Blog <http://miovision.com/blog> | **LinkedIn <https://www.linkedin.com/company/miovision-technologies> | Twitter <https://twitter.com/miovision> | Facebook <https://www.facebook.com/miovision>* ------------------------------ Miovision Technologies Inc. | 148 Manitou Drive, Suite 101, Kitchener, ON, Canada | N2C 1L3 This e-mail may contain information that is privileged or confidential.

[Users] Memory usage
by Koen Vanoppen 12 Feb '14

12 Feb '14

Dear all, When we monitor one of our machines, we noticed that there was one vm that was constantly giving a error of memory usage. But when we took a look at it, there is actually nothing wrong with it. Now we looked furhter then that. We looked at the API of the machine and noticed something very strange: <statistic href="/api/vms/3b9aa245-75ff-42e8-b921-1c9ce61826bf/statistics/b7499508-c1c3-32f0-8174-c1783e57bb08" id="b7499508-c1c3-32f0-8174-c1783e57bb08"><name>memory.used</name><description>Memory used (agent)</description><values type="INTEGER"><value><datum>*-944892806* </datum></value></values><type>GAUGE</type><unit>BYTES</unit> It's a negative... What could be the problem? Kind regards, koen

[Users] oVirt 3.4 test day - results
by Alexander Wels 12 Feb '14

12 Feb '14

Hi, I tested the following items during the test day and here are my results: 1. "reboot VM" functionality The related feature page is: http://www.ovirt.org/Features/Guest_Reboot The feature page mentions a policy selection checkbox which I was unable to find in the web admin UI at all. I checked the patches that implement the feature and did not see the check box implementation. The patches did show me that all I need to use the feature was to install the guest agent on the guest. So for my test I installed a fedora guest, and I installed the guest agent on the guest. After about a minute after starting the guest, the reboot button was enabled and pressing it started the reboot sequence on the guest. I had a console open on the guest and it informed me that the admin had started the reboot process and the guest would be rebooted in a minute. I did not find a way to change the time it took for the reboot to happen. I did the same test with the REST api, with the same result. The reboot was scheduled for a minute after I issued the command. I did not find a way to change the time with the REST api either. I am guessing that is a future feature. 2. Fix Control-Alt-Delete functionality in console options I had trouble getting spice to work in my test setup, but no issues with VNC. So I tested VNC. I checked the VM console options to make sure that 'Map ctrl-alt-del shortcut to ctrl+alt+end' was checked. Then I connected to a running VM with VNC. I pressed ctrl-+alt+end expected it to issue a ctrl-alt-del to the guest. Nothing happened. I pressed ctrl-alt-del and it properly issued ctrl-alt-del to the guest. I made sure there was no issue with my client by using the menu to issue a ctrl-alt-del to the guest which also resulted in the proper action on the guest. I opened a bug for this: /https://bugzilla.redhat.com/show_bug.cgi?id=1057763/[1] I did this test on my Fedora machine, and the description mentions that certain OSes capture the ctrl-alt-del before sending it to the guest, Fedora is not one of those OSes, so maybe my test was not valid? 3. Show name of the template in General tab for a VM if the VM is deployed from template via clone allocation. This is a very straight forward test. I created a template from a VM. I named the template. Then created a VM from that template using clone allocation. I verified that the name of the template is now properly shown in the VM general sub tab. Works as expected. Overall I had issues getting engine installed due to the shmmax issue reported in other threads, and then I had a really hard time adding new hosts from a blank fedora minimum install. I was successful one out of three attempts, which I feel was probably an yum repository issue as I was getting conflicting python-cpopen issues causing VDSM to not start. Thanks, Alexander -------- [1] https://bugzilla.redhat.com/show_bug.cgi?id=1057763

[Users] [ovirt-test-day-2] - testing neutron integration - remove external networks
by Omer Frenkel 12 Feb '14

12 Feb '14

Hi, I tested $subject, I have to say i don't know much about networks / neutron, so maybe some of the issues i encountered are just my fault.. i used pre-configured neutron server (thanks Mike!) and the beta2 for ovirt-engine, i used the wiki to configure it: http://www.ovirt.org/Overlay_Networks_with_Neutron_Integration these are the issues i've seen: 1. add provider is hidden, since 'system' node in the tree is collapsed by default, i couldn't find it, the way to add provider should at least be documented in the neutron integration wiki, i had to ask around to find it.. 2. add provider dialog: wrong tab indexing - after entering name, i clicked 'tab' to enter description, but the focus moved to the 'cancel' button [bug 1064240] this is pretty minor, but i think its basic usage issue, and probably easy fix. 3. selecting 'Subnet' sub-tab of the imported external network doest show anything, and creates an error in the engine log [bug 1064231] Other than that, i was able to create and remove the external network with no issues, we might need a better (maybe step-by-step?) documentation on configuring this, as it was not trivial (there are manual steps need to be done on the hosts..) or, even better, automating everything needed on the host side into host-deploy. Thanks, Omer.

by Moti Asayag 12 Feb '14

12 Feb '14

Hi, In the 3.4 ovirt-test-day-2 I've tested the all-in-one feature. I installed the all-in-one setup on a vm. The installation ended almost successfully, except of the vdsm service, where the the host didn't become operational due to lack of support in clusterLevel >= 3.4: Feb 11 15:51:52 localhost vdsm root ERROR VIR_MIGRATE_ABORT_ON_ERROR not found in libvirt, support for clusterLevel >= 3.4 is disabled. For Fedora 19 users, please consider upgrading libvirt from the virt-preview repository Once I created a new 3.3 DC and configured a local storage, the local host become operational and I was able to create a vm and to run it. Thanks, Moti

I have retired "host01" and would like to remove it completely: [root@host03 ~]# hosted-engine --vm-status --== Host 1 status ==-- Status up-to-date : False Hostname : host01.example.com Host ID : 1 Engine status : unknown stale-data Score : 2400 Local maintenance : False Host timestamp : 1390840600 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1390840600 (Mon Jan 27 17:36:40 2014) host-id=1 score=2400 maintenance=False bridge=True cpu-load=0.0034 engine-health={"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} gateway=True mem-free=127844 --== Host 2 status ==-- Status up-to-date : True Hostname : host02.example.com Host ID : 2 Engine status : {"health": "good", "vm": "up", "detail": "up"} Score : 2400 Local maintenance : False Host timestamp : 1392129793 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1392129793 (Tue Feb 11 15:43:13 2014) host-id=2 score=2400 maintenance=False bridge=True cpu-load=0.0057 engine-health={"health": "good", "vm": "up", "detail": "up"} gateway=True mem-free=107251 --== Host 3 status ==-- Status up-to-date : True Hostname : host03.example.com Host ID : 3 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 2400 Local maintenance : False Host timestamp : 1392129796 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1392129796 (Tue Feb 11 15:43:16 2014) host-id=3 score=2400 maintenance=False bridge=True cpu-load=0.0134 engine-health={"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} gateway=True mem-free=127838 Thanks - Frank
